I'm quite impressed by the changes that you have made to the updated pdf versions. In addition to fixing a lot of bigger things, you have also taken some fairly minor comments and "this would be nice to have" type of ideas and incorporated them into the books. Thank you very much!
A couple of things popped up as I leafed through the new copies:
In book 2, the alien contact timeline on page 5 and the chronology of contact timeline on page 84 remain contradictory, even after the update. For instance, the first table says that contact with the Sung was first made in 2259, while the latter puts it to 2248. It doesn't help the confusion that the body text in the Sung description gives a third date: 2247.
In book 2, it looks like you have removed all "Compatibility" ratings for colonies. Was there something fundamentally broken with them? I quite liked the idea to be honest. Note also that on page 101 you still have the text that tells us how to use those compatibility numbers, even if those numbers no longer exist anywhere, as far as I can see.
A similar thing has happened in book 1 with the Wakizashi. The weapon has been removed from the stats and the pictures, but the short description still remains in the body of the text.
King's survival DM is now listed as 4 in the colonies list. Should probably be -4?
Finally, I suppose we just have to agree to disagree about many of the hyphenations and other punctuation.

But I can certainly live with that.
Great work!
